Surgical shadowless lamp, an indispensable medical lighting equipment in surgical operation. With the continuous development of medical technology, the performance indicators of surgical shadowless lamps are constantly improving to meet the increasing requirements of doctors for surgical shadowless lamps
In the 1950s, in order to improve the illuminance of the shadowless lamp, the hole-type multi-lamp shadowless lamp was successively produced and used in Europe and Japan. This type of shadowless lamp increases the number of light sources, and uses high-purity aluminum as a small reflector to improve the illuminance of the shadowless lamp. However, due to the increase in the number of bulbs of this type of shadowless lamp, the temperature of the shadowless lamp rises quickly, which is likely to cause discomfort to the doctor and dryness of the tissue at the operation site, which is not conducive to the postoperative recovery of the patient.
In the early 1980s, the daily newspaper began to produce cold-light aperture surgical shadowless lamps with halogen light sources. In the late 1980s and early 1990s, the overall reflective surgical shadowless lamp came out. This shadowless lamp uses computer-aided design technology to design the curved surface of the reflector. The curved surface is formed by industrial stamping at one time to form a polygonal reflector. The light source of this shadowless lamp is not only as bright as daylight, but also without shadows.
The world's earliest surgical shadowless lamp was invented in the United Kingdom by French professor Wayland in the 1920s. He put a 100-watt light bulb on the dome of the shadowless lamp at the center of the refractive lens formed by many narrow flat mirrors evenly placed, so the entire shadowless lamp is in a cone shape with a sharp tip removed. The second reform of the shadowless lamp was the single-lamp shadowless lamp in France and the track-type shadowless lamp in the United States in the 1930s and 1940s. At that time, the light source used incandescent bulbs, the power of the bulbs could only reach 200 watts, the filament winding area was large, the light path could not be controlled, and it was difficult to focus; the reflector was polished with copper material, which was not easy to reflect, so the illuminance of the shadowless lamp was extremely low.
In the 21st century, the details of surgical shadowless lamps have been continuously optimized. In addition to the improvement of basic performance parameters such as illuminance, shadowlessness, color temperature, and color rendering index, there are also strict requirements for the uniformity of illumination. In recent years, LED light sources have been used in the medical industry, which has also brought new opportunities for the development of surgical shadowless lamps.
In recent years, LED shadowless lamps are slowly occupying the market. They have excellent cold light effect, excellent light quality, stepless adjustment of brightness, uniform illuminance, no screen flicker, long life, energy saving and environmental protection.
Our company mainly produces and sells operating room equipment, including operating lights, operating tables, and medical pendants. Our products have entered major hospitals at home and abroad. This week, our colleagues took our products into the comprehensive operating room, cosmetic surgery hospital, reproductive center in Suzhou, Jiangsu, and the products were well received. We walked into the hospital and communicated with the dean, hoping to make progress with everyone. We will continue to optimize our products so that more people can know and use our products.
